Quick Answer: Windows typically run $200 to $1,200 per window, with vinyl replacement units landing $300 to $700 and wood or fiberglass units pushing past $1,200. Price moves with frame material, glazing, size, energy rating, and install type. The ranges below are general estimates based on publicly available data, get current quotes from your suppliers for accurate bids.
What Drives the Price
Six things move a window price, and you should know all six before you bid:
- Frame material: vinyl is the value default, wood and fiberglass sit in the middle, aluminum and clad wood sit at the top. A vinyl double hung runs $250 to $600, a wood double hung runs $500 to $1,200, and a fiberglass casement runs $600 to $1,400.
- Operating type: fixed (picture) is cheapest because there is no hardware. Single hung and slider are next. Double hung, casement, and awning add hardware and run higher. Specialty shapes, bay and bow assemblies, and folding units carry the biggest premiums.
- Glazing: single glazing is rare in modern spec work. Double pane insulated glass units are the standard. Triple pane adds $100 to $300 per window and cuts the U value further. Low E coatings and argon gas fill are common upgrades. Tempered or laminated glass for code required locations adds 25 to 60 percent to the glass cost.
- Size: standard sizes are commodity. Specialty widths, oversize units, and custom shapes run 20 to 50 percent more. A 3 ft 0 in by 5 ft 0 in double hung is commodity, a 4 ft 0 in by 6 ft 0 in is custom.
- Energy rating: ENERGY STAR and local code compliance (U value, SHGC, air leakage) shape the glazing spec. Higher performance glass costs more up front but may be required by code in your climate zone.
- New construction versus replacement: new construction units come with a nail fin and install into the rough opening. Replacement (insert) units fit into the existing frame. Full frame replacement costs more in labor because you tear out the old frame.
Region, volume, and the commodity market still matter. Vinyl tracks resin pricing. Wood tracks lumber and millwork indices. A 50 unit multifamily package gets a volume break a single replacement never sees.
Typical Price Ranges by Type
As of 2026, common per window ranges run like this. Treat these as ballpark, your supplier quote is the real number.
- Vinyl single hung, 3050: $200 to $450 per EA.
- Vinyl double hung, 3050: $300 to $600 per EA.
- Vinyl slider, 6050: $350 to $700 per EA.
- Vinyl casement, 3050: $400 to $800 per EA.
- Wood double hung, 3050: $500 to $1,200 per EA.
- Clad wood casement, 3050: $700 to $1,500 per EA.
- Fiberglass casement, 3050: $600 to $1,400 per EA.
- Aluminum fixed (picture), 6050: $500 to $1,200 per EA.
- Bay or bow assembly, 6 ft wide: $1,000 to $3,500 per EA.
- Triple pane adder (any of the above): $100 to $300 per EA on top of double pane.
- Tempered glass adder: 25 to 60 percent over standard glass, required near doors, stairs, and wet areas per code.
How to Calculate the Quantity You Need
Take the count straight off the window schedule on the plans. Every opening listed is one window, and the schedule gives you type, size, glazing, and sometimes the U value target. Group the count by type and size so you price each group at its own range. A job with twenty 3050 vinyl double hungs and two 6050 picture windows does not average out cleanly, price each size group separately.
Apply a small waste factor. Windows do not break often, but a cracked insulated glass unit or a frame damaged in transit happens on big jobs. One to three percent is typical for tract work, zero to one percent on a custom single family with careful handling. Round up to the next whole window.
Tie the count to the sheet it came from. Window schedules change in revision, and a single added 6050 picture window can move the line item $1,000. Keep the window, rough opening prep, and flashing lines separate so a substitution late in the job does not blow the budget silently.
How to Buy Smarter
- Get three quotes, every time. Window prices move 10 to 30 percent between suppliers in the same city. The lumberyard, the window distributor, and the manufacturer rep all quote differently.
- Bundle the window package. Put every window on one purchase order. Package discounts on a full house order are real, single window orders rarely see them.
- Verify the energy code early. Your climate zone sets the U value and SHGC targets. Substituting a lower grade unit to save $80 fails inspection and costs more in the redo.
- Decide new construction versus replacement up front. New construction units have a nail fin and go in during framing. Replacement units fit the existing frame and go in during finish. The labor and the line item are different.
- Lock the quote for 30 to 60 days. Vinyl tracks resin pricing and wood tracks millwork indices, both move. A held quote protects your margin on longer bids.
- Check lead time on custom sizes. Specialty widths and shapes can run six to ten weeks. Order early or you hold the siding and drywall schedule.
Where Estimators Get It Wrong
The most common miss is averaging across sizes. A job with fifteen 3050 vinyl double hungs at $400 and three 6050 picture windows at $1,000 averaged at $500 looks fine, but the picture window spec alone is $1,500 above the average line. Price by size group, not by average.
The second miss is forgetting installation. A window price with no labor, no flashing, no sealant, and no interior trim is not a complete opening. New construction install commonly adds $80 to $200 per window in labor. Full frame replacement adds $200 to $500 per window.
The third miss is the rough opening. Sheathing, house wrap, flashing tape, and sill pan flashing are not in the window price. They are separate line items and they add up. Skip them and your waterproofing line is short.
The fourth miss is tempered glass. Code requires tempered or laminated glass near doors, stairs, bathtubs, and wet areas. Tempered glass adds 25 to 60 percent to the unit price. Read the schedule notes and the code, do not assume standard glass everywhere.
Putting It Together
Windows look like a simple count line and they are not. Price each type and size at its own range, separate the unit, the install, the flashing, and the trim, carry a small waste factor, and lock your quote. A clean window package on a single family home commonly lands between $6,000 and $25,000 total, depending on count, type, and size. Get three quotes, tie the count to the window schedule, and price the opening complete, not just the unit. That is how you keep the window line defensible.
